My invention relates to a machine for forming cotton-seed meal, &c., into cakes prior to putting it into the hydraulic press to remove the oil therefrom, and for trussing casks, barrels, te

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the dra-wings, A represents the frame of the machine,supporting a stationary table, I3, a driving-shaft, C, in boxes C', and a cam-shaft, D, in boxes D. The shaft C has a pinion, B, meshing into a cog\vheel, D2, on the shaft D, and .it also has a drivingpulley, B,

H represents a sliding table supported by the stationary table, it having rails or strips H' on its under side fitting on rails A on the upper side of the table B,the outside rails, H', having grooves to receive projections on the rails A', as shown in Fig. l, so that while the table II is free to slide back and forth, yet it is held from lateral movement. This movable table is pulled out from under the platen onto the exposed part A2 of the stationary table to receive the meal, and then is moved back under the platen, so that the meal will be pressed into a cake by the descent of the platen.

I represents the platen,to which are secured 5o upwardly-projecting beams I', preferably hollow, as shown in Figs. l and 2, to allow the pieces J ,secured to the frame A,in which they have vertical movement, being raised by a spring, L, secured to the top or upper part of the frame A, to which they are connected by rods L' L, and being forced down by cams N on theshaft D. which, as the shaft is turned, come against friction-rollers O on pins or short shafts O', that pass through the beams I'. (See Fig. l.) These cams thus force the platen downto press the meal, and as soon as they pass the rollersl the spring L raises the platen, as stated. I preferto have four of these camsone on each side of each beam-and there is, of course, a friction-roller, O, for each cam. The upward movement of the platen is limited and regulated by a set screw, P, passing through the lower cross-piece J. (See Fig. 1.).

This lower cross-piece is alsoprovided with friction-rollers J', journaled in lugs J2, secured toor formed upon hthe cross-piece. These rollers are located at the openings in the cross piece through which the beams ofthe platen pass, as shown in Figs. 1,2, and 3, and on theopposite sides ofthe beams from the cams N. The cams naturally shove the beams away from them, or have a tendency to do so, and the rollers receive this strain or pressure, thus avoiding the friction that would be incident to a xed support or bearing. The crosspieces J have lugs J* to receive bolts J3, by which the cross -pieces are secured to the frame A.

I will nowdescribea clutch device by means of which the camshaft is connected to and disconnected froin the driving-shaft at will. The cog-wheel D2 is loose upon the shaft D, audits hub D3 has a notch or recess, D". (See Figs. l, 6, 7, and 8.) Trepresentsacollarsurrounding the shaft, and keyed or otherwise secured to it, as shown in Figs. 4 and 5. In this collar is a slot, T', receiving a sliding block, U, with a head or projection, U', as shown most plainly in Figs. S and 9. When not pulled and held out by a dog or pawl, V, the end ofthe block is forced into the notch DL of the hub of the cog-wheel by means of a spring, U2, (see Figs. Sand 9,) and when in this position it locks the cog-wheel to and causes it to turn with the IOO shalt, and it will remain in this position as long as the dogVisheld in the positionshown in Fig. 5, where it is out of engagement with thebloelcbeing held in this position by it being` pivoted at V to the frame A, and connected by means of a cord or rope, Y?, to a treadle, V, which is depressed by the foot ot' the operator. As soon as the pressure on the treadle is removed,the upper end of the dog1 is pulled down from the position shown in Figs. 5 and 9 to the position shown in Figs. 4 and 8 by a spring, U, or otherwise. The next time the block comes around after the dog is thus pulled down its head or projection, U', comes in contact 'with the taperingV or inclined end V* of the dog, (see Figs. 6 and 7,) and is forced back out of engagement with the hub of the cog-\vheel, thus allowing1 the wheel to turn without turning the shaft. As soon as the upper end of the dog is raised again and the block comes around opposite the notch in the hub, the spring,r U operates the block, as stated. The block is held to the collar and the collar strengthened by a ring, WT. One beam only could be used, and by making` the table H vertically adjustable, as shown by dotted lines, Fig. 1,(the table B being removcd,) and changing slightly the :Form of the platen. the press makes a good machine for trussing casks, barrels, die.

As an equivalent ol' the spring L a weighted lever may be used, or a weight connected to thel platen by a rope passing over pulleys.

I claim as my inventionl. In a press, the combination of the fixed table, movable' table, platen provided with beams having friction'rollers, cams secured to a revolving shaft and adapted to depress the platen, and the spring to which the platen is connected and by which it is raised, substantially as and for the purpose set forth.

i3. ln a press, the combination olvl the lined table, movable table, perforated platen, hollow beams secured to the platen, cross-pieces secured to the frame ol-` the machine, frictionrollers secured to the beams, cams secured to a revolving;` shaft, and adapted to depress the platen by bearing against the friction-rolIers, and the spring to which the platen is connected and by which. it is raised, substantially as and for the purpose set forth.

3. In a press, the combination of the tixed table and movable table, platen, beams secured to the platen, perforated cross-pieces secured to the l'rame ot' the machine and through which. the beams pass, friction-rollers secured to the lower cross-pi ece and agili nst which the beams bear, trictioli-rollers secured to the beams, cams secured to a revolifing shaft and adapted to depress the platen, and spring' to which the platen is connected and raised to its upper position, substantially as set forth.

Ll. In a press, the combination ot' the movable table, platen provided with one or more supportilig-beams, cams secu red to a revolving shaft, and adapted to depress the platen by pressing against bearings on the beam or beams, and a spring, or its equivalent, to which the platen is ebnneetei'l, and by which it is raised alter beine` forced down by the cams, siibstantially as and i'or the purpose set lfort h.
